The FAA this week granted a supplemental type certificate (STC) for installation of Garmin’s GTX 345 ADS-B In/Out and the GTX 335 ADS-B Out transponders on more than 60 models of helicopter. The approval is expected to provide a simplified path to ADS-B certification for aircraft on the Part 27 approved model list (AML).
